No honey involved, but along the same theory of getting the local pollen inside of you etc, try going to a herbal doctor and getting some sort of tea made from local flowers, I do this when my hay fevers bad and it's always worked for me..

I use the Boots hayfever relief syrup which contains Loratadine without lactose - at about £5 for 100ml (10 doses) it's not cheap but non of the other stuff seems to work for me. (I think it's meant for kids.)

My Mum is a qualified acupuncture person now, so if you do ever get over this way maybe she can help... she also waffles on about your chi being low etc but so long as you dont listen to the nonsense it might help...
